Overview
The Fair-Rite Products Corp. model 2620021802 is a round cable EMI suppression core designed for free-hanging installation. It functions as a ferrite shield bead to mitigate electromagnetic interference on cables. The component is manufactured using Fair-Rite material system 43, which provides high permeability for effective noise suppression in the MHz frequency range. This solid core allows cables to pass through its center bore without requiring disconnection of the circuit.
Feature Summary
- Provides electromagnetic interference suppression for cables passing through the core
- Utilizes Material System 43 for high magnetic permeability characteristics
- Features a solid round design suitable for free-hanging mounting applications
Applications
- EMI suppression on data and power cables
- Noise reduction in electronic equipment wiring
- Cable shielding in communication systems
Procurement Notes
Verify the specific Fair-Rite material number associated with this part number to ensure compatibility with your target frequency range. Confirm that the physical dimensions match the cable diameter requirements of your assembly. Check current availability status directly with the manufacturer or authorized distributors, as lead times may vary based on production schedules.
Selection Notes
Select this component when a non-invasive method for adding common-mode choke functionality to existing cabling is required. Ensure the inner diameter accommodates the cable bundle size. Consider the impedance characteristics of Material 43 relative to the noise frequencies present in your application environment.
Part Context
This part belongs to the Fair-Rite family of ferrite cable cores. These components are widely used in electronics manufacturing for passive filtering. The 26 series designation typically indicates specific dimensional standards within the manufacturer's product line for round solid cores.
Replacement Considerations
Consult Fair-Rite official documentation for direct cross-reference part numbers. Verify that any substitute maintains identical inner diameter, outer diameter, and length specifications to fit existing mechanical constraints.
